INSTRUMENT FOR INDIVIDUAL VARY-SIZING OF TYPE Ajiplicationfiled June 25,

This invention relates to thereproduction of type or matrices of sizes varying from an original copy, or for reproducing in varying sizes any other matter involving the necessity of-an instrument or apparatus as hereinafter more particularly described. j

" In particular my invention usually relates' to enlarging, to any desired size, printed co'pysof'letters or words ordesigns by producing a matrix in zinc or other suitable plate ready for printing, and to so reproduce with economy and speedand atlthe same time with great accuracy. For example, I may have'letters or a word or designv with type ofa standard font, but require for the particular job'double the size or even three times or four-times the size, or only a slightly'enlarged or reducedtype for some advertising arrangement or for. display on circulars, or

- simply an enlarged heading for pamphlets or books. Ordinarily heretofore the enlarged type requires even for a single word,

an entire available'font of type of thelarger size. This means that on the chance of re- 3 quiring various sizes, it has heretofore been necessaryto have a number of different sizes of fontsalthough only a few of the letters .may be necessary for the particular job, and furthermore to meet the usual requirements two fonts of each of the larger sizes are a necessary equipment of a printing shop handling this class of work.

. By. my invention only the standard size of type'is necessary, because my apparatus permits the enlargement of a. few letters, and as much and as little as needed, and the reproduction in zinc to provide the matrix for the enlargement or the varied size can-be produced quickly and cheaply and an exactduv plicate of the original in design. In practical use. this apparatus thus supplies a much needed want with the elimination of many sets of fonts heretofore necessary, as well as V the facility for reproducing to anyintermediate size or exact multiples of the original letters, figures, drawings, etc. 1 r 'One form of instrument embodying my invention is shown in the accompanying -.drawing in which: U i l v Fig. I isa perspective of my instrument tus.

Fig. IV is a fragmentary View, enlarged, of the adjusting means for the instrument arm rest. I

In this particular form shown, a fixed post 1 pivotally supports an arm 2 having secured to its other ,end ,a post 3 with an 5 anti-friction base 4;, which may be a ball orballs suitably mounted'to support the weight but permit entire freedom of motion of the post over thetable or board 5. At the swinging end ofarm 2 another longer arm 6 is 7'0 pivoted, preferably .at the junction of post 3, and nearthemidde of arm 2 another arm 7 is adj ustably pivoted with a readily clampingwing nut 8' or similar set screw permitting sliding of the arm 7 and pivoting at 8."75

This arm has a handle 9 adapted for con- "venience andfirm'grip for the, guiding of the end ofTa'rm 7, with this grip so located as not tointerferewith visibility of the stylus or pointer-10. This stylus is mounted near the end of arm 7 and at the junction therewith of arm 11, and it is securely supported by the chuck or similar means 10 so that the stylus may be changed, for use of. different sizes'or for replacement" and also for vertical adjustment. Above thearms 7, and 1 1 is preferably a bracket 12to more rigidly secure the upperextension -10 of the stylus support.

The arm 11 is turn is secured to arm 6" which preferably has a slot 6 and the two arms are interconnected by a'bolt or screw with wing nut tightening means '13, so that it may readily be clamped tight with respect to the longitudinal adjustment in the slot 6', but when clamped as to position the bolt or other fastening means are of such a charac ter as to permit swiveling freely.

The arm 6 extends far beyond the junction with armll, and on this extension is mounted 1 a bracket 14 which in conjunction with the arm proper provides a support for the means 15 necessary to rotate the drill or cutting tool 16. This preferably includes a clutch 17 adapted to readily clamp a dia-' mend drill of the finest size, and alternately a larger cutting drill of the kind used for routing out the surface of a zinc plate in order to leave the type or reproduced design in relief. This drill chuckor other suitable support is driven by a flexible shaft 18 having a union 19 at its end adapted to be readi- 1y detached when secured for operation by set screw 19. At the other end of the flexible shaft isa motor 20 with suitable circuit connections and switch, whereby the motor can be readily driven electrically and under the control of the operator, preferably vlocatedon the same worktable as a separate.

base so as not to permit any jar or vibration ofthe motor to the stylus or the drill, and so as to better insure accuracy in operation of reproduction. 7

The. arm 6. also extends beyond the drill bracket and this extension 21 is made so long that it overhangs a supporting sill 22 having a smooth upper surface permitting free sliding of the; arm 21. This overhanging arm end 21 furthermore not sufficient length to afford a grip by the operator, or a suitable hand-hold or knob is secured to, this overhangingend so that the operator may ease the motion of this arm and steady the arm as it moves, in order to assure uniform and true reproducing movement of the drill while cutting the enlarged or vary-sized matrix, letters, figures, designs, etc. The sill is preferably in two parts, abase 23 adapted to be readily secured to the workbench, an adjust-v able top part 23" with a spring 24 pressing the upper section up, and a stop screw 25 limiting the motion, with a set screw 26, if desired,;to fix the position. This sillthus provides means whereby the operator may force cutting drill to rent the zinc deeper,

'and' in any case to provide for the control of cutting depth of the routing tool.

It will thus be seen that my apparatus consists generally of a substantially adapted pantograph having one corner mounted to oscillateon a fixed post,'and with the stylus or guiding point supporting at one corner of the pantograph members adapted to be guided by a suitable group accurately along the lines of the c'opythat it is desired to reproduce in varied sizes, as shown in the perspective yiew. The readily adjustable arms determine the ratio of movement given to the drill, and graduations, asshown, adjacent the slots for adjustment of'the arms permit settlng the instrument for any desired definite amplification of the reproduction. The

motor wi h the flexible shaft drives the drill on the reproducing arm, but permits freedom ofmotlon so that the drill will be moved in exact accord with the copy as the stylus is moved along the outline of the letters or figures of the original.

In operation, one hand holds the grip close to the original copy, and the other steadies and regulates the pressure or depth of cut effected by the drill, 'While still permitting the drill to move in every direction in exact accord with the movement of the stylus, but in amplified degree as predetermined by the setting of the pantograph arms. I find that after a little practice the stylus can be readlly moved accurately along the outline of copy, and the other hand unconsciously moves and steadies the cutter supporting arm moving with it in the amplified degree, and assuring uniform and exact reproduction'cutting on the zinc or other -material desired for the matrices. In operation I insert a fine prefer- I ably diamond drill to cutthe outline, then when this is completed I remove the diamond drill from the chuck and set arouting cutter in position of a suitable size sothat with a changed stylus, to correspond, I then move the stylus over the area to be routed, and themaking of the enlarged or vary-sized'matrix is completed in perfect design andform and is ready for usein the usual way.

It willbe noted, as shown n that both arms 2 and 7 have related slots and the drawing,

also graduations adjacent the slots,'which permit adjustmentof the armsto an exact predetermined relative position. This is also the case with slots and graduations on arms 6 and 11. Thus the adjustment of the arms'or bars can be made to assure exactly the relation desired for proper functioning, and specifically for the purpose of giving the exact proportion of increase desired in the reproduction. I have also used'arms having a series of separate holes drilled in the positions which would give a certain definite but limited number of variations in size. With holes on these arms they have to be separated for adjustment to different s1zes, and the slotting-a d graduations thusprovide simplicity and ease of adjustment with accuracywhich better suit my purpose in making this instrument most convenient for universal use in this work.

It will also be noted that. if it i d i d t *11 reduce the size of copy, I would position my stylus on the last armextension in place of the chuck for the cutting tool, and the cutting tool and drill would be accommodated at the joint where the stylus is supported i the form shown in the drawing. Thus the instruer cutting tool for routing purposes.

While various changes in design may be made and details of construction may be used to produce my instrument for commercial use or for special work, such changes may be made Without departing from my invention,but what I claim and desire to secure by Letters Patent is:

An instrument having a pantograph with a fixed pivotal support, a table for copy and matrix support in substantially the same plane, a reproducing drill-supporting arm forming a part of said pantograph having a I freely floating table engagement near one end, a sill for the engagement of the other end of said arm adjustable for a normal cutting position of the drill and yieldable to permit variable depression of the arm simultaneous with its guidance for routing, an intermediate drill chuck carried by said arm suspended between said two supports and flexible driving means actuated by a remotely supported motor, said sill having members resiliently pressed apart, and adjustable means limiting their movement away from each other.

In testimony whereof, I have signed my name to this application, this 19th day of May 1927.
